I don't need to look anything up to know there was no 4-bolt SJ production SBC engine. 327 or otherwise.

actually in 1964 there was infact a 4 bolt main 327 suffix code T0221hv it was made specifically for the corvette 350 hp manual trans duel point ignition built in totawan ny

A 4-bolt 327 SMALL JOURNAL. Now, THAT'S a new one!!!

There should be a suffix code stamped just in front of the passenger side cylinder head. Look that up and it'll tell you what you have. Or you can pull the oil pan off and check the casting number on the crank. Chances are very high that it's a 350 though. The 3970010 casting number was used throughout the 70s.
